' 3' Claims.

Thisinvention relates to `wall construction consistingof rectangularblocks adaptedltobe-laid in' structionthat all partsv may be .handledcon.4

veniently by a` single operator who mayfornilthe blocks completely atthe time they. are laid4 in the wall', this being an. advantage since aplastic: concrete ller is used for eachzblockf, and-thereby hardening oieach block ispermitted: while: building each course.

. 'Ihe invention includes deadzairspace or insulation for the inner sideof the'wall, .and includes other features of advantage as will. behereafter mentioned. The invention consists 'of-the. new and usefulconstruction, combination and. lar.-

rangement of parts asy described: and. claimed` herein, and asillustrated inv the accompanying. drawings, it. being understood thatchanges may.

be madeV in form, size, proportions and minor details of construction,said changes being within the scope of the invention as claimed.

Numeralllv indicatesstrips or sheets oiA wiremeslr which: are embedded-'in the side-plates,each havingendPportions I5. which. extend into the area between theside-plates, and at It are indi- In the drawings which illustrate oneembodiment of the invention, Fig. 1 is a vertical section on line I-I ofFig. 3, said View showing a pair of blocks, partly broken away, beingadded to show a lower horizontal course for a wall. Fig. 2 is asectional View showing spacing-means for maintaining the slabs orside-plates of a wall block in relatively parallel position.

Fig. 3 is a View of a block in longitudinal section on line 3--3 of Fig.1 to clearly show stabilizing devices for a Wall block.

Fig. 4 is a view in side elevation showing the use of wire-mesh forreinforcement purposes and Fig. 5 is a side view of a tool for temporaryuse in supporting the slabs or side-plates in parallel position.

The invention is shown and described in connection with rectangularblocks III adapted to be disposed one upon another in horizontalcourses,

the proportions or size for the blocks depending upon the height of thewalls to be built and use or occupancy of the building.

Each block consists of a pair of rectangular slabs or side-plates, theouter side-plate being indicated at II and the inner plate indicated atI2, the rectangular area between the plates being utilized forreinforcements.

cated anchor-members. made of Wire-mesh or otl'ier.` foraminous.material, partly embedded. in the,side1platesf and secured by use offasteners I1, to members. I5, .these members l5 having. end portionswhich. also. extend. into. the area between thexside-plates. .Thesesheets. |15- and IS. are mounted; mdwayfbetween their ends,y upon theanchor-units.

Numeralsil38-in'dicate .eye-bolts adapted to be threaded in the:anchor-nuts, and at I9 is indicated a spacing-bar having projections atits ends. for engaging in the apertures of the eye-bolts.

Cof-operating; devices,V suchv as recesses .2@ formjed in:the.horizontal?v edgesvof the side-plates andz suitable locking elements2 I therein, are' employed. The recesses of an upperblock are dis--posed -in'register w-ithqthe; recesses of a lowerblockgandgbyruse;ofmembers.2| the blocks of the several courses may bemaintained in vertical alignment.

Numerals 22 indicate upright reinforcing rods and at 23 are indicatedhorizontal reinforcing rods, these stabilizing elements being disposedbetween the side-plates for the several courses of a wall, the number ofthese elements 22 and 23, and their spacing depending upon thickness andheight of the Wall.

Numeral 24 indicates a filler for the areas between the side-plates, andthis ller and also the slabs or side-plates may consist of concrete orother suitable material.

The anchor-nuts I3 and I4 are disposed midway between the ends of theside-plates, and each anchor-nut I4 is threaded for receiving asupporting-bolt 25 Which projects outwardly of the side-plate I2 forreceiving and supporting a bearing-block 26, these bearing-blocks beingadapted to support an inner plastered Wall 21 or metallic lath for awall and to provide airinsulation space 28.

Numeral 29 indicates a tool for temporary use of an operator whendisposing the side-plates in parallel position. In operation the uprightstabilizing rods 22 may first be placed in position. When theside-plates of the blocks for =an upper course is laid upon theside-plates of a lower course, the recesses above mentioned may receivethe locking elements 2| so that the lower edges of the upper side-platesto be laid will be suitably supported. The tool 29 may then be used, thepairs of prongs 3D at the ends of the tool being disposed stridingly,and the length of the tool corresponding to the thickness of thebuilding block.

The side-plates being thus supported by use of ythe tool, it is obviousthat the eye-bolts may be rotated for suitable adjustments in theanchornuts, and the spacing-bar When placed in operative position willmaintain the side-plates relatively parallel. The tool when removed willpermit a horizontal reinforcing rod to be placed in position, and theadhesive ller may then be poured or deposited, and thereafter willbecome hardened for holding the parts in rmly connected condition as aunit.

Numeral 3| (Fig. 4) indicates apertures form-ed in the wire-mesh ofmembers I5 and I6 for receiving the anchor-nut I3 and I4.

Among some of the advantages to be derived by use of the invention itmay be stated that the costly wall forms usually employed are notrequired. Also all expensive wall finishing may be dispensed with, andthe outer slab or side-plate of each block may be nished before theblock is used, and may be provided with any selected color, texture orsurface treatment.

It is obvious that the wire-mesh between the side-plates of one blockmay extend to an adjacent block, and when the areas between thesideplates of the blocks have been lled With adhesive material, eachblock at its ends will be secured,

on account of this construction, with the ends of blocks adjacentthereto. Since labor of only ordinary skill is required, the use of theinvention will be an advantage as an expense-saving feature.

I claim as my invention:

1. In wall construction, concrete slabs laid in horizontal coursesproviding an outer and an inner Wall-section and a channel between saidwall-sections, anchor-nuts disposed opposite to each other embedded inthe wall-sections and extending to the channel, eye-bolts threaded inthe anchor-nuts, spacing-bars spanning the channel and mounted in theeye-bolts, sheets of Wire mesh mounted on the anchor-nuts each having apart embedded in a wall-section and having an end-portion extending intosaid channel, and concrete material in said channel for embeddingtherein the spacing-bars and end-portions of said sheets of Wire mesh.

2. In Wall construction, concrete slabs laid in horizontal coursesproviding an outer and an inner wall-section and a channel between saidwall-sections, horizontal stabilizing-rods midway between theWall-sections, vertical stabilizingrods in the channel intersecting thehorizontal stabilizing-rods, anchor-nuts arranged opposite to each otherin pairs and embedded in the wallsections, eye-bolts threaded in theanchor-nuts, spacing-bars disposed transversely of the channel andmounted in the eye-bolts, sheets of Wire mesh arranged in opposed pairs,the sheets of each pair being riveted to each other and mounted on ananchor-nut and having parts embedded in a Wall-section and havingrelatively spaced end-portions extending into the channel, and aconcrete iller in the channel for embedding therein the saidreinforcing-rods, portions of the eye-bolts, the spacing-bars and saidend-portions of wire mesh sheets. V

3. In Wall construction, rectangular, concrete slabs laid one uponanother providing a pair of relatively spaced, parallel side-sectionsand an intermediate channel, pairs of opposed anchornuts in theside-sections, eye-bolts-threaded on the anchor-nuts and extending intothe channel, spacing-bars each spanning the channel and de tachablymounted on the eye-bolts of a pair of opposed anchor-nuts, sheets ofwire mesh secured to each other in pairs and provided withA aperturesfor receiving the anchor-nuts therein, the sheets of each pair havingparts embedded in the side-sections and having end-portions disposed inspaced relation in the channel, and concrete material in said channelfor embedding therein the eye-bolts, said spacing-bars and the spacedend-portions of said sheets of wire mesh.
